coins & bitcoins

coins is a set of transaction construction libraries for UTXO-based chains. It aims to provide high-quality tooling for constructing transactions, and to enable use in the browser via wasm-bindgen.

Building & running tests

install rustup
Run all the tests $ ./build.sh
build the docs: $ cargo rustdoc

Project Goals

Easy to use Bitcoin tooling
Generic traits supporting multiple networks
WASM compatibility in all packages
Support essential BIPs

Project Architecture

The project is built around the coins-core crate which defines high-level traits and interfaces. Chain-specific libraries use these traits to provide a consistent developer experience across chains.

We have provided a bitcoins crate with a Bitcoin-targeted implementation. See its documentation for usage instruction and details.

Other than that:

coins-bip32 provides tooling for BIP32 HDKey derivation
bitcoins-provider gives a simple consistent interface to chain data with swappable backends.

Project Status

While this is feature-complete, and there are some tests, much of it is alpha software. There will be rough edges, and the interfaces are subject to change.

Specificallly:

core, bip32, and bitcoins are relatively stable.
provider is working, but does not yet have a stable API
ledger, and ledger-btc are essentially alpha
